Iinb
VCC/2
–
Input for I signal. This input
impedance is 200 kΩ. In the case of
that I/Q input signals are single
ended, amplitude of the signal is
500 m VP-P max.
–
Input for I signal. This input
impedance is 200 kΩ. In the case of
that I/Q input signals are single
ended, VCC/2 biased DC signal
should be input. In the case of the
I/Q input signals are differential,
amplitude of the signal is 500 m VP-P
max.
